Subluxation of unspecified cervical vertebrae, sequela

This code signifies a long-term effect or complication resulting from a previous subluxation of an unspecified cervical vertebra. It indicates that the initial injury has resolved, but residual symptoms or conditions persist due to the past subluxation. This code does not describe an acute or current subluxation.

Use this code when documentation clearly indicates a sequela (e.g., chronic pain, limited range of motion, neurological deficits) directly attributed to a prior subluxation of an unspecified cervical vertebra. The patient's medical record should specify that the original injury is no longer active and that the current condition is a residual effect.

• Always sequence this code after the code(s) describing the specific sequela (e.g., chronic pain, radiculopathy).
• Do not use this code for current or acute subluxations; refer to the acute S13.1- series for those cases.
• Ensure documentation explicitly links the current condition to a past cervical subluxation and specifies "sequela" or "late effect."
